RESIDUE AND WEED MANAGEMENT PRACTICES IN ZERO-TILL WHEAT (Triticum aestivum L.) UNDER RICE-WHEAT CROPPING SYSTEM
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 4
Abstract
A field experiment was conducted during 2005-06 to 2006-07 at Varanasi to find out the effect of three residue management practices viz. R1 (Residue Removal), R2 (Residue Retention alone), R3 (Residue Retention with Trichoderma) and four weed management treatments viz. W1 (Control), W2 (Hand weeding at 30 & 45 DAS), W3 (Isoproturon +2,4-D (1.0+0.5 ha-1 at 30 DAS), W4 (Fenoxaprop 120 g a.i. ha-1 fb Metsulfuron 4g a.i. ha-1) on weeds and productivity of zero-till wheat (Triticum aestivum L. emend Fiori & Poal) in rice-wheat cropping system during the winter (rabi) season. Weeds in weedy check caused 20.32 and 25.82% reduction in grain yield of wheat, respectively. Wheat grown under rice wheat cropping system with residue retention with Trichoderma application produced 6.8 and 8.2 % higher grain and 7.3 and 6.2 % straw yield over residue retention alone.
